Abstract:
In order to reduce calculating workload of failure types identification of single-layer spherical shells under harmonic loads, avoid repeating calculation and save after-treatment time, reliability indexes were proposed to determine failure type of structure by using response surface method and the specific step included three aspects. Firstly, reliability indexes which accord to the response surface method of single-layer spherical shell based on displacement failure mode were calculated under harmonic loads. Furthermore, the specific corresponding relations between reliability indexes and failure types were established. Finally, the quantitative indexes were provided to determine failure types of structure of single-layer spherical shell. The research shows that the method can determine failure types accurately and is effective and practical.
